EXHAUST APPARATUS FOR MINES.

Application filed December 28, 1912.

To all whom it may concern:

Be it known that I, BALINT Pnsxxis, a subject of the King of Hungary, residing at "Windber, in the county of Somerset and State of Pennsylvania, have invented certain new and useful Improvements in Exhaust Apparatus for Mines, of which the following is a specification, reference belng had therein to the accompanying drawing.

This invention relates to an exhaust apparatus for mines, and my invention aims to provide an apparatus that can be located in the entries, rooms and halls of a mine for exhausting fire damp, explosive and other gases that are detrimental and unsafe to miners.

My invention further aims to provide an apparatus of the above type that is inexpensive to manufacture, durable, and easy to install in the workings of a mine or quarry.

My invention will be hereinafter specifically described and then claimed, and reference will now be had to the drawing, wherein there is illustrated a plan of the apparatus, which is partly broken away and partly in section.

The apparatus comprises a main exhaust pipe 1, having the inner end thereof provided with branches 2 and the outer end flared or funnel-shaped, as at 8. The main exhaust pipe 1 can occupy the main entrance or shaft of a mine with the flared end thereof exhausting to the atmosphere. The branches 2 of the main pipe can extend into the rooms or workings of a mine. The main pipe, adjacent to the flared end thereof is provided with an angularly disposed blow pipe f in communication with a blower or fan 5 that blows air through the pipe 4 to create a suction in the main pipe 1. The blower or fan 5 is of the ordinary and well known type ordinarily used in mines. The

Specification of Letters Patent.

Serial No. 739,601.

main pipe 1 is in communication with a tank or reservoir 6 that is located adjacent to the flared end of the pipe and at a point to collect gases that are drawn into the main pipe 1. The tank 6 has the bottom thereof partly closed, as-at 7 and said tank has exhaust cocks 8.

When the apparatus is placed in operation, gases and fumes will be collected in the tank or reservoir 6 and such gases or fumes as fail to enter this tank or reservoir exhaust to the atmosphere. The exhaust cocks 8 permit of the gases or fumes within the tank or reservoir 6 being tested from time to time to determine the nature of the gas liberated in the workings of the mine.

The apparatus in its entirety can be made of metal and the main pipe 1 and the branches thereof in suitable lengths or sections whereby the apparatus can be installed throughout a mine.

hat I claim is A gas exhausting apparatus for mines comprising a longitudinally extending mine exhaust pipe adapted to be positioned in the main entrance of a mine and having an outer end portion concavo-convex in longitudinal section, said end portion offset with respect to the remaining portion of said pipe, a tank integral with said pipe in proximity to said end portion and communicating with the pipe, a rearwardly extending inclined pipe opening into the inner terminus of said end portion, a blower communicating with the inner end of said inclined pipe, and exhaust cocks carried by said tank.

In testimony whereof I affix my signature in the presence of two witnesses.
